The blower / air blower member 3 includes a blower / air blower head assembly and a rotary holder 31. The rotary holder 31 is fitted with a ball plunger block 311 and a fixed holder 312. The ball plunger block 311 is fitted with a plurality of locking grooves 3111. The blower / air blower head assembly includes a motor cover 32 fitted on one side of the rotary holder 31, the motor cover 32 having a ball plunger slot 322 and a motor cover toothed portion 321 connected to the rotary holder 31 on one side. A spring 323 is attached to the ball plunger slot 322, and a ball plunger 324 fitted into the locking groove 3111 is fitted on the spring 323. In this embodiment of the blower, the rotation of the motor cover 32 can be fixed by a fixed holder 312 installed in the rotating holder 31. The motor cover 32 is connected to the rotating holder 31 by a ball plunger 324 installed on a spring 323 that fits into a locking groove 3111. When the operator presses the fixed holder 312 to make the motor cover 32 rotatable, the entire motor cover and air supply / exhaust head assembly can be operated and rotated. This drives the ball plunger 324 to compress the spring 323 and rotates the ball plunger block 311 to different locking grooves 3111. This engages the ball plunger 324 with the locking grooves 3111 at different positions, enabling flexible rotation of the air supply / exhaust head assembly. This allows for cleaning of narrower and hard-to-reach corners, expands the cleaning range of the blower, makes operation convenient, improves cleaning efficiency, adapts to various cleaning scenarios, and meets the diverse needs of the user. The motor cover 32 is connected to the rotary holder 31 by the motor cover toothed portion 321. The connection is stable and tight, reducing the gap between the motor cover 32 and the rotary holder 31. This avoids vibrations that occur during use, improves cleaning efficiency and user convenience, and the simple structure makes it easy to assemble, increasing production efficiency and reducing production costs.

Between the motor cover 32 and the rotating holder 31, they are rotatably connected by passing through the motor cover 32 and the bearing 314 with the bolt 313, and the structure is simple. Between the motor cover 32 and the rotating holder 31, the motor cover 32 is fitted and fixed by a fixed holder 312, or loosened to adjust the angle. The operation is simple and convenient, and it is convenient to quickly fix or adjust the angle of the air blowing / sucking head. A cover cap 3131 is installed on the top of the bolt 313, which is convenient for operating the bolt 313 to realize the connection or disassembly between the motor cover 32 and the rotating holder 31.

[0023] In some specific embodiments, one side of the rotary holder 31 is inserted into and connected to the motor cover toothed portion 321 by a bolt 313, and the rotary holder 31 is equipped with a meshing portion that fits into the motor cover toothed portion 321, thereby connecting the rotary holder 31 and the motor cover 32 through the motor cover toothed portion 321 to the meshing portion, resulting in a tight and robust connection.

[0024] As shown in Figure 6, in some specific embodiments, the number of locking grooves 3111 is 10, and the adjacent locking grooves 3111 are arranged at equal intervals along the circumferential direction, which is convenient for positioning the motor cover 32 at multiple different angles relative to the rotary holder 31. Optionally, one side of the motor cover 32 is provided with multiple sets of circumferentially arranged ball plunger slots 322, springs 323, and ball plungers 324, each ball plunger 324 fitted to correspond to a different locking groove 3111, and after operating and rotating the entire motor cover and air supply / exhaust head assembly, the ball plungers 324 are fitted to correspond to the different locking grooves 3111 after rotation, thereby improving the stability and reliability of the positioning of the motor cover 32 relative to the rotary holder 31. In some other embodiments, the number of locking grooves 3111 may also be set to one or other quantities.

[0025] As shown in Figure 8, in some specific embodiments, the connecting assembly 4 includes a connecting rod 41 and a connecting member 42, and the connecting rod 41 adjusts the distance between the blower / suction fan member 3 and the handle 2 by the connecting member 42.

The male connector 421 and the female connector 422 are connected by a threaded sleeve 423. Since the male connector 421 and the female connector 422 are connected to two adjacent connecting rods 41 respectively, and then the male connector 421 and the female connector 422 are fixed with the threaded sleeve 423, assembly and disassembly can be performed quickly, improving the operator's efficiency. The installation of the threaded sleeve 423 allows the male connector 421 and female connector 422 to be secured using a screw-tightening method, resulting in a tight and stable connection. Additionally, by adding nuts, the male connector 421 and female connector 422 can be locked together to prevent loosening of the connection.
